WHAT NERVES COULD BE CAUSING MY HEADACHES & WHERE ARE THEY LOCATED?
The nerves causing your headaches are typically located in one of four different locations within the head and neck region. The first site is between the eyebrows, also known as the glabella. The nerves that can become compressed in this area are known as the supraorbital and supratrochlear nerves. These two nerves can become pinched by the muscles in this area that cause the frown lines, by tight connective tissue and/or bone at the orbital rim (top of the eye socket). The next site is the temple region and the nerves which can be compressed in this area are called the zygomaticotemporal nerves and auriculotemporal nerves. These nerves can become compressed by one of the muscles used for chewing (the temporalis muscle) or by a blood vessel which can compress or wrap itself around one of these two nerves or its branches. A third area that can be a trigger zone for chronic headaches is the back of the head and the nerves in this region which can be the cause of trouble are known as the greater, lesser and third (or least) occipital nerves. These nerves can be compressed (i.e. pinched) by the strong neck muscles which can be in spasm, by the tight connective tissue that surrounds them or by other small blood vessels which can wrap themselves around these nerves as well. Finally, nerves within the inner lining of the nose can also become irritated and result in chronic headaches such as migraines.
